Hydrosorbent Desiccant Silica SG750
Hydrosorbent silica gel products are simple to use and offer lifetime protection. A colored indicator shows when they need to be reactivated - safely and easily, right in your conventional kitchen oven. There is never any need for refills or replacement parts.
This heavy duty unit provides lifetime protection for closets, lockers, cabinets vaults and safes. The unit is preferred by police armories, hospitals and museums as well as individual collectors of firearms and artifacts. The large canister contains 750 grams of silica gel packaged in a steel can that measures 4" x 6", about the size of a coffee can. Protects 57 cubic feet of enclosed space.
What to do when the indicator shows that the silica gel is saturated:
Remove the bag of silica gel granules from the carton (never, ever, put the carton containing the bag of crystals in the oven!) and place the bag in a vented 240 degree F oven for at least 3 hours. Replace the bag in the unit. Please note that it may take several hours for the indicating circles to turn blue again.
After reactivation is complete and the unit is cool enough to handle, return the unit to the enclosed space you wish to protect immediately. If you leave the unit in the open it will rapidly absorb moisture from the surrounding air.
Buy it once, use it forever.
